questions, answered
The things people ask before they book. If yours isn't here, get in touch — we'd rather talk it through than have you guess.
What is knob-and-tube wiring?
Knob-and-tube wiring was installed between the 1880s and the 1940s — the first generation of home electrification. The system lacks proper grounding, and its insulation is brittle and prone to cracking and breaking down, which causes hazards and electrical issues. We recommend replacing it.
Should my knob-and-tube wiring be replaced?
Yes. For most homes that still have it, that is 120-plus years of use. The insulation becomes brittle and breaks down, causing electrical fires and hazardous conditions in your home. Multiphase Electric has 20-plus years in the remodeling industry and hundreds of homes improved. We can replace your old wiring in under a week in most cases, depending on the size of your house.
How long does a panel replacement take?
A panel replacement usually takes 8 to 10 hours, and you should expect to be without power for that duration. We tell you the window before we start so you can plan around the fridge and anyone working from home.
Can you provide a Level 2 EV charger?
Yes. Multiphase Electric LLC can supply any ChargePoint charger for your EV. If you already have a charger you'd like to use, we can install that for you as well.
Whole-home standby generator or portable — which is best for me?
Either way, we can help you make the right decision for your home and your area. Physical space requirements, fuel availability — natural gas versus propane — and cost all drive the decision. We'll do a free assessment of your home or business and provide an estimate.
Can the Wi-Fi signal in my home be improved?
Yes. Most homes run a single Wi-Fi router that can't cover every area. We can supply and install a mesh system, or work with your existing one, to create a wired backhaul — running Ethernet through select areas of the house. A wired-backhaul mesh handles gaming, streaming, and casual browsing all at once, as long as your service provider can support it.
